Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a water-based metal anti-corrosion and heat-insulating coating for petroleum equipment and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and social production, energy and the environment have become two major issues of increasing concern to the whole society, and higher requirements have been put forward for energy conservation and environmental protection. In recent years, more and more metal materials have been used in production plants and temporary architectural buildings, especially for some petrochemical storage tanks, pipelines and open-air reactors. High temperature will also bring hidden dangers of production accidents and excessive energy waste. Therefore, it is necessary to use air conditioning or water spraying to cool down in the hot summer. A lot of energy is consumed. Based on this, wat...
